symfony4 - Route is in debug list but returns 404 in Symfony 4

Question

Ok, so I just installed latest version Symfony 4. Run the browser after installation and a nice welcome greeting shows. All good!

Then I created a new controller using make:controller. I named this controller Client and is using Annotations, same with the other Default Controller. I configured the routing as follows:

/**
 * @Route("/client", name="client")
 */
public function index()
{
    // replace this line with your own code!
    return $this->render('@Maker/demoPage.html.twig', [ 'path' => str_replace($this->getParameter('kernel.project_dir').'/', '', __FILE__) ]);
}

I refreshed the browser and all good, no errors.

Then I manually typed the path into the browser to check if it's really working:

localhost:8000/client

Problem. The url returned standard apache 404

Not Found
The requested URL /client was not found on this server.

Apache/2.4.18 (Ubuntu) Server at new.staff-fdr.dev Port 80

The debug route sees this though:

-------------------------- -------- -------- ------ ------------------
  Name                       Method   Scheme   Host   Path   

 -------------------------- -------- -------- ------ -----------------
  client                     ANY      ANY      ANY    /client  
  index                      ANY      ANY      ANY    /       
  _twig_error_test           ANY      ANY      ANY    /_error/{code}.
